<P>PROBLEM TO BE SOLVED: To determine the secular deterioration of the hinge mechanism of a radio communication terminal by providing the hinge mechanism capable of detecting an angle and utilizing the hinge mechanism, and furthermore, to optimize radio communication by turning an antenna to a suitable direction. Ž<P>SOLUTION: The hinge mechanism 130 includes a fixed part 250, a rotary part 260 freely rotatably fitted to the fixed part 250, a plurality of grooves 262 formed at the outer edge of the rotary part 260, a coating film 264 formed in the grooves 262, and a hooking part 252 provided in the fixed part 250 and engaged with the groove 262 through the coating film 264 to hook the rotary part 260. The coating film 264 formed in the groove 262 is formed so as to have a resistance value different from that of the coating film 264 formed in the adjacent groove 262.
